Yamaha G16e - new batteries little power

[tilsonm]

I'm new to golf carts. Just bought a 1999 Yamaha G16e. The batteries were shot. I replaced all 6 just 2 weeks ago. After brief usage, I charged them for the first time. The charger said 15.6 hours before it turned off (my cart is out of town at a recreational dwelling).

The thing seems ok on flat surfaces but has no hill power. A, 8% incline slows it to a walk.

I'm suspecting the motor. Anyone have ideas?

Thanks,
Mike T

Is the cart lifted? What size tires do you have? Do you have the flip flop back seat?

[tilsonm]

Not lifted. Just a regular old golf cart of the course. Standard tires, no back seat.

I am fairly new to the cart world myself, but I think you first need to verify that all of your new batteries are good. If you can get your hands of a load tester, and get a reading on all of your batteries. Once you have ascertained that all of your batteries are good, I would check your cables to make sure they are all good and clean. If you are using #6 gauge cabling, I would upgrade it to at least #4 gauge. As far as testing to see if you need to check your controller or motor, I know there are far more experienced people on this site that can chime in on that one. Good luck

Did you replace the cables when you replaced the batteries?

I'm having the same issue with power for my 97 G16E. I just picked it up last night for a great price. It has no pull on inclines and slows even more when weighed done. I have old batteries, which I need to get tested before I make the purchase and it's not the problem.

Check the forward/reverse, it is probably bad and not making full contact. Scottyb just built a hd one.
